The rapid nascence of data availability, powerful algorithms, and quantitative methodology are necessitating novel conceptualisations of “digital”, serving both as an applied means of constructing information and as an arena for critical inquiry into emergent modes of representation. With a broad focus on the interplays between human health and social/built/natural environments, the Digital Health Geographies Research Group explores the confluence of applied machine learning and the analysis of situated, community-scale sociocultural practice through empirical study.
REKKE – Resilienz durch Kulturlandschaft im Klimawandel
Die Auswirkungen des Klimawandels in Bayern bedeuten in der Zukunft eine Tendenz zu länger anhaltenden Hitzephasen im Sommer mit teils deutlich über 40°C. Dadurch steht Kulturlandschaft in ihrer resilienzstiftenden und gesundheitsfördernden Wirkung für die Bevölkerung vor großen Herausforderungen. Es geht dabei nicht nur um den Verlust einer vertrauten ästhetischen Qualität, sondern um konkrete Einschränkungen als Erholungsort, Ort sozialer Teilhabe und Raum für körperliche Aktivität und Sport. Dies betrifft die Nutzbarkeit des heimischen Balkons genauso wie sommerliche Freiluftveranstaltungen oder die wöchentliche Walking-Gruppe im nahen Wald. Die Folgen des Klimawandels treffen dabei nochmals verstärkt vulnerable Bevölkerungsgruppen, die ohnehin nur eingeschränkten Zugang zu gesundheitsfördernden Kulturlandschaftselementen haben.
VIBRANCE – Violence in Brazil: Analysis of Community Environments
Brazil is known worldwide for its vibrant cultural diversity and beautiful landscapes. However, increasing awareness of deeply embedded social issues such as social inequality, poverty, and violence underscores the need for more nuanced understandings of their interrelations with space and place. VIBRANCE is a collaborative study bringing together researchers from Brazil, Germany, and Canada to develop and implement innovative interdisciplinary approaches to studying space, place, and violence. By using advanced quantitative techniques and situated qualitative inquiry, VIBRANCE assesses various domains of social and spatial risk factors of violence at multiple scales across the country, seeking to advance understandings of the complex geographies of violence and to identify policies and programmes to reduce the burden of violence in Brazilian communities.

Narratives of Crisis
Using COVID-19 as an example, the Digital Health Geographies research group uses automated knowledge mining methods to investigate, on the basis of different types of text, (1) which spatial-cognitive strategies are used to consistently locate crises outside one’s living environment, (2) which events modify these narratives over time, and (3) how newly emerging arguments discursively re-bind these events. The aim of the study is to alleviate the socioeconomic consequences of crises by revealing the suspensive character of certain narratives for necessary political decision-making processes.
STAGE – Spatial Transcoding of Artificial Geographical Environments
Open Worlds, Digital Landscapes: digital inscriptions of cultural mythologies in playable open worlds and built environments.
In the field of Place Research, visual spaces, both real-world and artificial, provide a stage for shared social practice. There exist different forms of visual spaces, ranging from complete virtual worlds over augmented reality to geoservices, which add digital information on site.
Individual practice is bound to the participant’s specific experiences and cultural context. As it can be revealed by the metaphor of game and play, we explore how these aspects are represented, expressed, and enacted in different game environments. Derived questions cover: How is space used as an element within the game to create a flow state, which binds the player to the game?
- Daniel Sonnenwald, BA Thesis: „A GALAXY FAR FAR AWAY… “: Space Syntax and Critical Theory as a Framework to investigate the Spatiality in the Medium of Video Games.
Drawing on a geographical interpretation of Star Wars Jedi: Fallen Order, the author investigates the functionality of space in video games. How is space used as an element within the game to create a flow state that keeps the player engaged in the game? How is affordance created and communicated through digital architecture? How is the spatial Design understood as part of the games narrative and how does it incorporate political and social layers? In the eyes of the author, a combination of approaches from critical theory and the analysis of space syntax is the means of choice to investigate these questions.
- Lukas Suk, BA Thesis: Roles of Landscape in Red Dead Redemption 2
In this bachelor thesis, the author analyses video games through a landscapes lens, focussing on Red Dead Redemption 2, combining theoretically supported geographical perspectives with the conceptualization of game development and game design on the concept of landscape. Using an analytical methodology, the author aims to discuss the purposes of landscape in Red Dead Redemption 2, considering the functions of individualization, immersion, and value mediation and the means by which these functions can be implemented.
- Bryan Maland, BA Thesis: Geographische Analyse des Videospiels Red Dead Redemption 2 mithilfe der Prospect Refuge Theory
Video games have long since ceased to be purely entertainment media. This thesis shows that video games are receiving more and more attention in a global context and should therefore take up an increasingly larger part in the research context. The goal of this work is to decode the semiotic sign systems of video games, which are consciously or unconsciously inserted into the game by every game designer, using Prospect Refuge Theory. As an example for this analysis, the game Red Dead Redemption 2 from Rockstar Games was chosen. In this game you act as Arthur Morgan, an outlaw in the Wild West of America in 1899. The picturesque landscape and the survival game principle leave a lot of room for interpretation of Appelton’s theory. The entire space of the Open World is divided into smaller individual rooms in order to make up Prospect, Refuge, and Hazard Spaces. These spaces can then be viewed from different perspectives. In the game it would be either the view of Arthur Morgan or that of a First Nations (North American indigenous) person. The application of the theory, i.e. the identification of the individual spaces, is only possible through the imbued realism of spaces that Rockstar has added to the game. Ultimately, it must be recognized that video games today, due to their their semiotic effects, set a valuable example that can have a polarizing effect on players.

PURE SPACE – Prospective Urban and Rural Epidemiology: Spatial Analysis of Cardiovascular Environments
This project seeks to disentangle the complex relationships between socioeconomic status, the built/natural environment, and chronic diseases, specifically focussing on cardiovascular disease and diabetes mellitus risk factors. Using epidemiological techniques and machine learning, we develop socioeconomic and environmental indices to estimate the spatial component of CVD risk. This project is being conducted as part of the Prospective Urban and Rural Epidemiology (PURE) Study.

GEM – Greenspace Exposure Modeling
In what ways does greenspace influence human health?
Urban greenspaces such as parks, trees, gardens, or green roofs may have a positive effect on physical and mental health. However, the pathways concerning how greenspaces promote health are often complex. For example, higher availability of vegetation contributes to improved air quality and reduces the effects of urban heat islands, access to public parks can provide opportunities for exercise and community building, and higher visible greenness in daily life may reduce stress and anxiety.
By 2030, 60% of the worlds population will be living in urban environments and even though greenspaces have the potential to buffer the adverse health effects of urban living, studies suggest that this potential often remains underutilised. It is thus important to understand the different types of greenspace exposure (e.g. Accessibility, Availability, and Visibility of Greenspace) and their underlying pathways to assist decision makers and urban designers in their efforts to build healthy and sustainable cities.
In this project we investigate these complex relationships and effects on human health by building spatial algorithms to improve Greenspace Exposure Modeling.
